Nvidia nForce 700i in the test: three-way SLI and PCIe 2.0
The test mainboard
To be able to use three-way SLI , XFX includes a 'normal' SLI bridge as well as one for the use of three graphics cards with our copy of the text. A small top-mounted fan for the triangular heat sink over the 'System Platform Processor' (SPP) and nForce 200 is also included. Our first few minutes of operation with the 780i SLI actually showed quite high temperatures when we finger tested the heat sinks, which we will measure precisely with our infrared thermometer at a later date. Only a few days ago the first results of three-way SLI became known . However, the nForce 680i was still used there.
A look at the chip trio of the nForce 780i SLI offers the good one on the MCP, as expected old label NF570-SLI-N. Compared to the MCP on the 680i SLI (A2 stepping), there has only been one revision jump (A3). SPP and nForce 200 are each available in revision A2. The 700i family officially supports the 45 nm CPUs Yorkfield and Wolfdale from Intel.
